Fantastic screenies, I'm so jealous right now! Very, very, very seldom do I see a Sylvari I actually think looks unique and interesting, but your guardian looks perfectly dramatic, perfectly dressed and perfectly outfitted. Looks good with and without the wings - they don't look like they are tacked on as an afterthought, so I would say wear 'em when you feel like it and hide when you don't! Rockin' either way.

Wings looks amazing at screens with dark and gloom theme.
I'm not sure about using them all the time (expect some fallen angel theme :D)
No matter you choose them or not is just amazing.
Perfect screens of perfect armor! :)

I'm always so happy and excited when I come on gw2style and I see there is a new look from you! xD
This one is amazing and unique...as always ;)
I love the dark theme and the ambience in your screens.. they are perfect!
As for the wings I think they look very good and fitting in this look. But if you're not totally happy with them maybe try Fervid Censer ? Or Canach's Backpack but not available yet..
Gold from me :)
